English words without vowels
English orthography typically represents vowel sounds with the five conventional vowel letters ⟨a, e, i, o, u⟩. The letter ⟨y⟩ is largely recognized as being a vowel in specific contexts, though often disregarded when talking about vowelless words, which typically focus on the absence of the main five.
